Add input label to Comments Form

[pwired]

Hi,
I am using the core Comments fieldtype in Processwire.
It has the default Form input labels Name, Email and Text.

This question has been asked before but I found no answer in the Forum section.
How can I add extra input labels to the Comments Form such as Country, Year. etc ?

Bumping this thread

If you cannot add extra input fields and labels to the core Comments Form to expand on it, for example Surname, Country, Month, Year, or any other custom field/label, etc etc then what is the use of having it in this limited way in the core ?

Would like to know who is using the core Comments fieldtype in Processwire and in what way, purpose ?
